Abstract

Se proporciona una bomba de paleta de capacidad variable (20) que tiene un anillo de control de bomba (44) que es movible para alterar la capacidad de la bomba (20). Una cámara de control (60) se forma entre la caja de la bomba (22) y el anillo de control (44). La cámara de control (60) es operable para recibir el fluido presurizado para crear una fuerza para mover el anillo de control (44) para reducir la capacidad volumétrica de la bomba (20). Un resorte de recuperación primario (56) actúa entre el anillo de control (44) y la caja (22) para desviar el anillo de control (44) hacia una posición de la capacidad volumétrica máxima. Un eje se acopla a un extremo en el anillo de control y un segundo extremo del eje se coloca a una distancia predeterminada desde el alojamiento (22). Un resorte de recuperación secundario (62) se monta sobre el eje y se configura para acoplar el anillo de control (44) después de que el anillo de control (44) se haya movido una cantidad predeterminada. El resorte de recuperación secundario (62) desvía al anillo de control (44) hacia una posición de máxima capacidad volumétrica. El resorte de recuperación secundario (62) actúa contra la fuerza de la cámara de control (60) para establecer una segunda presión de equilibrio.
